我正在我的应用程序中实现共享。使用 whatsapp、twitter 等应用程序可以共享图像+文本等混合内容，而 facebook、linkedin 等仅允许一种类型的内容（图像或文本）。如何做到这一点？Eg when whatsapp is selected it should send both, whereas when facebook is selected it should share text. 我想到的一种解决方案是查询所有可以执行此操作的活动，然后创建目标意图。以下是我迄今为止尝试过的

Intent shareIntent = new Intent(Intent.ACTION_SEND);
    shareIntent.setType("text/plain");
    shareIntent.putExtra(Intent.EXTRA_SUBJECT, title);
    shareIntent.putExtra(Intent.EXTRA_TEXT, title + "\n" + message);
    List<ResolveInfo> resolveInfos = activity.getApplicationContext().getPackageManager().queryIntentActivities(shareIntent, PackageManager.MATCH_DEFAULT_ONLY);
    ArrayList<Intent> mainIntentList = new ArrayList();
    Iterator<ResolveInfo> it = resolveInfos.iterator();
    while (it.hasNext()) {
        ResolveInfo localResolveInfo = it.next();
        String str = localResolveInfo.activityInfo.packageName;
        if (imageSupportingApps.contains(str) && (imageUri != null)) {
            Intent localIntent = new Intent(Intent.ACTION_SEND);
            localIntent.setComponent(new ComponentName(str, localResolveInfo.activityInfo.name));
            localIntent.putExtra(Intent.EXTRA_STREAM, imageUri);
            localIntent.setType("image/*");
            localIntent.putExtra(Intent.EXTRA_SUBJECT, title);
            localIntent.putExtra(Intent.EXTRA_TEXT, title + "\n" + message);
            localIntent.setPackage(str);
            mainIntentList.add(localIntent);
        }
    }
    Intent in = Intent.createChooser(shareIntent, "Share on ..");
    in.putExtra(Intent.EXTRA_INITIAL_INTENTS, mainIntentList.toArray(new Parcelable[localArrayList1.size()]));
    activity.startActivity(in);

更新 1： 这是我到目前为止所尝试的。但它只是发送文本。它不与 whatsapp 共享图像。
